This paper suggests a slotted ground ‘S’-shaped low profile planar microstrip patch antenna for wideband and high gain operation. The suggested has physical dimensions of 20mm×14mm×1.6mm having fractional bandwidth 111% the operating impedance 22.55GHz (9.12 GHz to 31.67 GHz). At 19 GHz, maximum 3.9 dBi is attained. An equivalent circuit model corresponding designed by ADS software assessed wit...
